TIME-DETECTOR FOR WATCHMEN.

SIEOIFICATION forming part of Letters Patent No. 648,249, dated April24, 1900.

Application filed August 29,1899. Serial No. 728,862. (No model.)

T0 to whom it may concern:

Be it known that I, EMIL EPPNER, watchmaker, of Konigstrasse 3, Breslau,German Empire, have invented new and useful Improvements inTime-Detectors for Watchmen; and I declare that the following is a fulland clear description of the same.

This invention relates to an arrangement of portable time-detectors forwatchmen by means of which the reliability of such apparatus is greatlyincreased. For this purpose a stop is arranged below the mark-pins to beactuated first by a key before the mark-pin can be pressed down.

The annexed drawings illustrate the object of the invention.

Figure 1 is awatchmans time-detector supplied with the new device inside view, and Fig. 2 in front view. Figs. 3, at, and 5 show the objectof the invention on a larger scale. Figs. 6, 7, and 8 suitably show thearrangement for a full key, while Figs. 1 to 5 show the arrangement fora hollow key.

ct are the spring-fingers, carrying mark-pins, and l) is a pin arrangedbelow these markpins. The pin 1) is attached to a turningpiece 0,pressed by a spring d against the wedge-shaped surface of aturning-lever e. The key, whether it be a full or a hollow key, isprovided with two bits. The one bit f is arranged at the end or nearthereto and when the key is turned correspondingly causes the part c tobe pressed in, which will swing the part c on its pivot and move the pinI) out of the path of the spring-fingers. The lateral projection orprojections coming in contact with one or more of the fingers will pressthe same inward until the mark-pins carried thereby perforate the strip,(indicated by the dotted line 0.) v

If one uses a full key, it is advisable to choose a construction similarto that shown in Figs. 6, 7, and 8. The key is guided at the rear by acap 2', provided with a front plate 70, which is turned by the key. Thedisk 70 has an incision on, into which the keybit f is inserted. As soonas the key is turned the cap 2', with the disk 7c, will also be turned.The disk is not perfectly circular, but cut off tangentially. This flatpart at is adjacent to the oblique surface of the lever 0 when in astate of rest. As soon as a turning of the key and the disk 70 takesplace the lever c is moved aside by the circular part of the disk k, inconsequence of which the pin 6 is drawn out of the path of the lingers,so that in continuing to turn the key bymeans of the bit 9 the pressingdown of the corresponding markpin may take place. The pin 19, coactingwith the operating parts therefor, constitutes a lock for thespring-fingers adapted to be operated to free said fingers when theproper key is used.

I claim-- 1. The combination with the spring-fingers and mark-pinscarried thereby of a lockingpin, a pivoted piece carrying the same, amovable piece adapted to operate said pivoted piece, a key for operatingthe former piece,and means for pressing the pivoted piece intoengagement with the movable piece.

2. The combination with the spring-fingers and mark-pins carried by thesame, of a stoppin normally in the path of said fingers, a pivoted piececarrying said pin having an inclined edge, and a movable piece withmeans for operating the same adapted to operate on said edge to movesaid pin out of the path of said fingers.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

EMIL EPPNER.
